ALEXANDER BAMAGE, OF RUSSELL GULCH, GOLOR kDO.

LAMP.

SPECIFICATION forming part of Letters Patent No. 280,240, dated June 26,1883.

Application filed March To all whom it may concern Be it known that I,ALEXANDER RAMAG'E, a citizen of the United States of America, re? sidingat Russell Gulch, in the county of Gilpin and State of Colorado, haveinvented certain new and useful Improvements in Lamps,

, of which the following is a specification, refer- Fig. 3 is aninverted or bottom View of the hood. Fig. 4 is a cross-section of theoil-fount.

The letter A designates the base or foot of the lamp; B, the oil-fountsupported thereon, and O a tube secured in any suitable manner withinthefount. The lower end of this tube has openings d, through which the oilin the fount passes to the tube. Vent-openings e are in the sides, nearthe upper end of the tube, to allow the escape from the fount of airwhen filling it with oil, and the upper end of the tube is entire- 1yopen. The tube 0 is filled with a packing, f, of cotton or othersuitable material, adapted to serve as a permanent feeder-wick, by whichthe oil ascends to the upper end of the tube say to the point Theoil-fount may be made of any suitable material-glass or metal-and in thepresent instance is provided with lugs h, (two or more in number,) whichproject laterally from the sides, near the bottom.

The hood consists of a cover or top plate, I, having a dependingcylindric jacket or wall, I, and is adapted to set down overthe'oil-fount.

- An ordinary lamp-collar, k, is attached to the central opening in thehood-cover, and the burner Lscrews, as usual, into said collar. The

hood is preferably made of metal, but may be made of other material.Openings n are provided in the hood-wall, through which the contents ofthe oil-fount may be viewed when A tube, J, is secured to the hood-coveror'to the collar,

and depends therefrom. (See Fig. 1, and also Fig. 2, where it isindicated by broken lines.) This tube is smaller than the tube G in theoil-fount, and is thereby adapted to enter or set down into the upperend of said tube telescope fashion. The lower end of the tube J isguarded by awire screen or perforated plate, 1), upon which rests anabsorption-pad, q, of cotton or other material. When the burner isscrewed into the collar, the usual wick is coiled up and occupies thespace in the tube J abovethe pad q. The lower part of the hoodwall hasan inturned flange, s, which fits closely about the exterior of theoil-fount, and is provided with notches h, through which the lugs h onthe oil-fount may pass. Upon the hood being set down over the oil-fount,the notches 'h allow the inturned flange to pass below the lugs, andthen by partly turning the hood on the fount the notches are turned toone side of and past the lugs. The latter then, by the flange beingbelow them, retains the hood on the fount.

It will be seen that when the hood and burner are in position on thefount the lower end of the tube J presses down upon the packing orfeedenwick f within the tube 0, the point 9 being the point of contactof the permanent feed-wick and the absorption-pad q. Thus the oil willpass from the 'feederwick to the pad q, and thence into the ordinarywick from which it is burned. The absorption-pad serves to hold storedup a certain quantity of oil, while the usual wick carries the oil tothe burningpoint.

Thus constructed, the hood and burner may be removed at any time fromthe oil-fount, even while the burner is lighted, and the supply of oilin the pad q and wick will maintain the flame for some minutes. I11 thisway, should the oilfount need replenishing at night, the light of theburner may be availed of to enable the filling to be done. The hoodmeantime being removed from the oil-fount will support the burner andpractically serve as a complete lamp. This feature of an oil-fount and adetachable top having an ordinary burner screwed into it is notdependent on the particu lar form of hood here shown. This general planmay be used without regard to the jacket 'or wall I and the inwardflange with notches h. There is no need to unscrew the burner for anypurpose except to put in a new wick. The packing or permanent wick f inthe tube of the oil-fount will prevent the oil from immediately flowingout should the lamp be accidentally upset.

In point of convenience, cleanliness in filling, and safety, the lamppossesses advantages.

Having described my invention, I claim and desire to secure by LettersPatent of the United States 1. A lamp having a base or foot, A, anoilfount, B, secured to the base, a removable cover or top for theoil-fount, provided with a screwcollar, k, for the connection of theburner, and means to secure the said cover to the oil-fount, as setforth.

2. A lamp having a base or foot, A, an oilfount, 13, secured to thebase, a removable cover or top for the oil-fount, provided with ascrewcollar, 1., for the connection of the burner, a

tube, J, depending below the collar, and hav ing its lower end guarded,and means to secure the said cover to the oil-fount, as set forth.

3. A lamp having an oil-fount provided with an upward-projecting tube,0, secured in the bottom, said tube having its upper end open, aremovable cover or top for the oil-fount, provided with a collar, 7c,and a tube, J, depending below the collar, and said tube adapted to setdown into the open upper end of the oilfount tube, as set forth.

4. Alamp having an oi1-fount provided with laterally-proj ecting lugs h,in combinationwith a hood provided with an inturned flange havingnotches h, as set forth.

In testimony whereof I affix my signature in presence of two witnesses.
